LeBron James made the Cleveland Cavaliers a title contender again this season, but the Cavs have yet to live up to expectations, creating speculation that the four-time Most Valuable Player will consider leaving in the summer.

James, who left Cleveland in 2010 and decided to return in the offseason, could become a free agent again after the 2014-15 NBA season. But while he previously said he will finish his career in Cleveland, Chris Haynes of Northeast Ohio Media Group said there is a chance James will bolt out again in the offseason.

"James, who turns 30 today, has no intention of compromising his prime years playing for a sputtering organization," Haynes wrote on Tuesday. "He can opt out of his contract at the end of the season and become a free agent."

The Cavaliers are currently in fifth place in the Eastern Conference standings with their 18-12 record. Sources told Haynes James will not hesitate to leave Cleveland again if things will not improve as the season progresses.

"Given the massive scrutiny he would endure if he departed Cleveland a second time, if his hand is forced, I'm told he won't hesitate to make the appropriate business decision if it means bolting," Haynes wrote.

James is averaging 25.2 points to go along with 7.6 assists and 5.3 rebounds per game this season. His numbers still make him one of the MVP candidates this season, but most NBA analysts have been questioning his desire to win since the season started, based on his body language.

ESPN reported Cleveland's struggles this season may have something to do with rookie coach David Blatt.

Sources said there is a growing concern about Blatt's ability to reach to his players, including James, but the 29-year-old superstar denied reports suggesting that he is not listening to his coach.

James said Blatt and the players are still in the process of building a strong bond, but he insisted his relationship with the first-year coach is getting better.

"I think my relationship with the coach continues to get better and better every day," James said. "This is two months of us being together. I don't know him fully. He doesn't know me fully. He doesn't know any of the guys fully and that's to be expected. It's our first year together. But he has our attention."
